Abstract

A tissue ablation probe is provided. The tissue ablation probe comprises an elongated shaft, at least one electrode tine carried by the elongated shaft, at least one tine exit from which the electrode tine(s) can be deployed from the elongated shaft and retracted within the elongated shaft, and a sheath covering the electrode tine exit(s). The sheath may, e.g., line an exterior surface of the elongated shaft or an interior surface of the elongated shaft. The sheath has at least one tine valve (e.g., a slit) positioned over the electrode tine exit(s) and configured to open when the electrode tine is deployed and to close when the electrode tine(s) is retracted.
